NAF Duball DL Ball Valves FCD NFENTB467-0-A4 /4 TECHNICAL BULLETIN Experience in Motion
Primary Characteristics NAF Duball DL is a full-bore ball valve which is equally suitable for isolation, on/off and modulating control applications. The NAF Duball DL is supplied as standard in stainless steel or carbon steel, but is also available in other materials, such as Duplex, titanium, etc. The NAF Duball DL is the fourth generation of the Duball portfolio, one of the most proven ball valve portfolios in the industry. The valve has: A spring loaded stem seal packing that provides a long, maintenance free and safe operation in automated on/off and control service Direct actuator mounting capabilities of the NAF Turnex actuator which provides a high performance, vibration resistant, compact valve package A sturdy, blowout-proof stem with a long foot providing a high torque transmission with a minimum mechanical backlash A floating ball that provides bidirectional tightness The unique Z-trim option that minimizes cavitation and noise and has excellent control characteristics An extensive size range, DN 5 400, size to 6 An easy-to-service arrangement, due to the off-center joint face of the valve body, which allows for easy replacement of the ball and seals, without the need for removing the stem and actuator Metal seats with a rigid welded overlay of or alternatively, metal encapsulated, reinforced seats A wide range of optional versions, including fire safe tested versions acc. to API 607/ISO 0497 CE-marked according to Pressure Equipment Directive (PED 97/3/EG) module H, category III.

Seat Rings Other versions Metal seat standard Soft seat standard Scraper seat Seat ring with scraper edge. Option: S Sealed seat Seat rings with two O-rings to prevent media penetrating behind seat ring. Used with media that crystallize. For temperature limitations, please see code 8 in the product code. Option: T Spring loaded seat main- If the differential pressure is low (below 0,5 bar) and a specified tightness must be tained, O-rings or springs must be fitted behind the seat rings. Option: E For temperature limitations, please see code 8 in the product code. W (Wave spring) max 50 C Locked seat rings All valves are prepared for locking of the seat rings in the form of peening-over. Option: L Degreased for oxygen service. NAF Duball DL has an option D which needs to be specified for oxygen service. In this version all components are de-greased before assembly and a special grease, which is approved for oxygen service, is used in assembly. Option: D Explosive atmosphere when intended for use in an explosive atmosphere, please specify option XA. With this option, the valve is certified according to ATEX 94/9/EC II G/D c. Option: XA Fire safe version NAF Duball DL is available in fire safe versions tested according to API 607, 6th edition (soft seated versions) and ISO 0497:00 (soft and metal seated versions). For a list of approved versions, please contact your Flowserve NAF representative. Option: Z (only together with stem seal F in code 9) Straight cylindrical flow path for sizes DN300 400 / 6 For sizes DN300 400 / 6 the balls are delivered as hollow balls in the standard version. Option -C specifies a solid ball with a straight cylindrical flow path, normally used for applications such as blow-down and discharge valves. Option: C flowserve.com 5

Actuators The pneumatic actuators NAF Turnex can be directly mounted to the NAF Duball DL without any couplings or brackets. Together with the direct mounting capabilities of all NAF positioners and several of the Flowserve positioners (PMV P5/EP5, PMV D3/D0 and Logix 50 MD+), this provides a high performance, vibration resistant and compact valve package suitable for precision control. Please see data sheet for further information on the NAF Turnex actuator capabilities and all other available accessories. 4
